FEEDBACK REDUCTION IN COMMUNICATION SYSTEMS

摘要

The present invention relates to a method for processing a microphone signal and a system for audio signal processing with feedback reduction. The method comprises processing the microphone signal by an adaptive feedback suppression filtering means; processing the microphone signal by an adaptive feedback compensation filtering means; and wherein the processing by the adaptive feedback suppression filtering means is performed in dependence on the processing by the adaptive feedback compensation filtering means. The system comprises an adaptive feedback compensation filtering means; and an adaptive feedback suppression filtering means configured to be adapted on the basis of the adapted filter coefficients of the adaptive feedback compensation filtering means.
